As you probably read in my other threads of questions, I recently top swapped and cammed (xp) my GT. Well the SD headers are out of stock atm, and am curious if i can just port the front manifold myself and do a u-bend delete and be safe until the Headers come back into stock. I'm running the stock pulley by the way. I read on another forum that it should be alright but i would like to double check with you guys first.
